One problem related to o2 sensor has been reported for the 1998 Dodge Ram 1500. The most recently reported issues are listed below.
Back in may 08 speed sensor went out then abs sensor went out a few days later causing no power brakes and could have cause my wife to have a wreck. Both replaced. Now getting engine codes for O2 sensors and truck sputters and cuts out and will not accelerate over 30 mph. Replaced sensors. Now receiving codes for pcm and now replacing. This is beginning to concern me. Will the next problem cause an accident.
